PET Scans are widely used for detecting cancers or abnormalities in brain function in humans and animals. The animation shows a small amount of a short-lived radioisotope injected into the body via a carrier molecule such as glucose. Glucose then carries the positron emitter to areas of high metabolic activity, such as a growing tumour.
